车床上使用的软三爪,由于有结构简单、定位精度高、使用方便等优点,所以得到了广泛的应用。要车配好软三爪,应注意以下一些问题: 一、软三爪材料及结构的选择 1.软三爪的材料有中碳钢、铝合金、铜合金以及胶木等多种。常用的是中碳钢和铝合金。选择时,一般根据工件的情况决定,若工件刚性好,不易变形,宜采用中碳钢制成的软三爪;若工件刚性差,易变形,则采用铝合金
Soft three-jaw lathe used, due to the simple structure, high positioning accuracy, ease of use, etc., so it has been widely used. To car with a good soft three claws, should pay attention to the following questions: First, the choice of soft three claw material and structure 1. Soft three claw materials are carbon steel, aluminum, copper alloy and bakelite and other. Commonly used in carbon steel and aluminum. Select, the general decision according to the workpiece, if the workpiece rigid, not easy to deformation, should be made of soft carbon steel jaw; if the workpiece rigid, easy to deform, the use of aluminum alloy
